Second-level liquid slag cache system with flow and temperature monitoring and control functions

2:

• The second-level liquid slag cache system with flow and temperature monitoring and control functions, as recited in claim 1, wherein:
• at least one non-contact slag ladle liquid level monitoring device (2) and at least one burner (3) are located at a top of the slag ladle casing (1) for monitoring a liquid level of liquid slag in a slag ladle and heat replenishment of the liquid slag in the slag ladle, respectively.

4:

• The second-level liquid slag cache system with flow and temperature monitoring and control functions, as recited in claim 1, wherein:
• the sizing nozzle (6) and the stopper head (7) are made from a refractory material with corrosion resistance, the stopper rod (9) is made from a high-temperature resistant metal material, the stopper rod (9) is in threaded connection with the stopper head (7).

5:

• The second-level liquid slag cache system with flow and temperature monitoring and control functions, as recited in claim 1, wherein:
• a layer of insulation material is coated on the slag control tube (11).

7:

• The second-level liquid slag cache system with flow and temperature monitoring and control functions, as recited in claim 6, wherein:
• when a flow of the slag exceeds a preset value, the stopper control mechanism (8) goes forward to reduce the flow area between the stopper head (7) and the flow passage within the sizing nozzle (6), so as to further reduce the flow of the slag;
• when the flow of the slag is lower than the preset value, the stopper control mechanism (8) goes backward to enlarge the flow area between the stopper head (7) and the flow passage within the sizing nozzle (6), so as to further increase the flow of the slag.

8:

• The second-level liquid slag cache system with flow and temperature monitoring and control functions, as recited in claim 1, wherein:
• the slag control tube (11) is located at a side of the slag ladle casing (1).
